Hardness testing machines for metals

At GNEHM, we specialize in providing high quality hardness testers designed for accurate and reliable testing of metals. Our hardness testing machines support various standardized methods, including Rockwell, Vickers, Brinell and Knoop, ensuring compliance with international testing standards.

Our product range of hardness testers

Our product line includes three main types of hardness testers, each tailored to specific testing needs and material characteristics. Specifically, these include:

1. Rockwell Hardness Testers: ideal for testing metals with varying hardness levels, offering quick and direct readings. 
2. Vickers Hardness Testers: suitable for small or thin metal specimens, providing precise measurements. Our Vickers machines can also be used for Knoop hardness tests.
3. Brinell Hardness Testers: best for testing metals with coarse structures or uneven surfaces.

In addition, we offer a range of consumables such as indenters and test blocks to support your hardness testing needs.

How our hardness testers are used

GNEHM hardness testers ensure material integrity across a wide range of applications. For instance, Rockwell testing (ASTM E18, ISO 6508, JIS Z2245) is widely used to verify the durability of components such as gears and bearings. For assessing coatings and thin materials in electronics, the Vickers method (ASTM E92, ASTM E384, ISO 6507, JIS Z2244) is often the preferred choice. Engineers typically assess heavy-duty components like castings and forgings using Brinell testing (ASTM E10, ISO 6506, JIS Z2243). Additionally, Knoop testing (ASTM E92, ASTM E384, ISO 4545, JIS Z2251) supports the evaluation of thin films used in medical devices.

Overall, early detection of weak points across all methods helps prevent failures and reduce production costs.

The importance of metal hardness testing

Metal hardness testing is critical in determining the ability of a material to resist deformation, wear and tear. It ensures that metals meet the requirements for specific applications, maintaining safety, reliability and performance standards across various industries.
